V. SYSTEM CONCEPTS
A. System Design Features
The DCM series Digital Cinema Monitor has many unique features which combine to make this the
most cost effective and versatile systems solution in the industry. This system addresses the following
needs:
Installer Feature
Provides Monitor and Crossover functions in one box.
Minimizes the amount of cabling required. (only one cable per amplifier contains
two signal inputs, two signal returns, power on/standby control and two channels of
load monitoring!).
Minimizes setup time (especially in megaplexs with similar rooms).
Preprogrammed speaker setting database for most common theater speaker brands
and models (supplied by QSC).
Indicates if something is wrong with the sound system (plus gives simple diagnostics to
help find problems).
An emergency bypass system allows center channel sound to pass through the system
even if there is a major problem.
Allows easy routing and crossover adjustments.
Protects system adjustments from tampering.
Sound quality is state-of-the-art (high dynamic range).
Projectionist Features:
Easy to verify that all of the audio in the theater is okay.
Automatic monitoring will light an LED if there is trouble with a speaker output.
A backup system (emergency bypass) can be easily activated.

1. QSC Amplifier DataPorts

The QSC DataPort connectors greatly reduce the complexity of wiring between the DCM unit and
the amplifiers. These DataPorts replace the need for preparing XLR or screw terminal connections
for the main amp audio inputs AND they replace the connections required to monitor the outputs
of the amplifier speaker connections. Another unique feature of the QSC Cinema System is the
ability to automatically analyze voltage and current status to determine shorts or opens in the
speaker cables. All of these connections are completed via the ONE DataPort mass termination
cable. A VGA computer monitor cable (15 pin male to computer monitor cable (15 pin male to
computer monitor cable (15 pin male to computer monitor cable (15 pin male to computer moni-
tor cable (15 pin male to 15 pin male) can be used, but verify that all pins have "unique" connec-
tions on both sides of the cable. QSC can supply these cables with high quality shielded audio
